Application: Citric acid monohydrate may be used:
• To prepare citric acid solution employed in the acetone method of 68Ga pre-purification and radiolabeling technique.
• To prepare Tris-citrate buffer employed for the electrophoresis of bacterial enzymes.
• To improve the release of diltiazem hydrochloride from melt extruded matrix tablets.
General description: Citric acid monohydrate(CAM) is an organic acid. It can be produced by crystallization from mother liquor of citric acid solution at 20-25°C during citric acid synthesis. Its molar enthalpy of solution in water has been reported to be ΔsolHm (298.15K, m = 0.0203molkg-1) = (29061±123)Jmol-1. An investigation of its crystal growth kinetics indicates that growth is linearly dependent on size.
